EarthCam has been pointing its robot eyes turned San Francisco Oakland Bay Bridge ward since 2008, and in that time it's collected some 2 million images of the £4.1 billion project. Put together in sequence, they're stunning.

The newly finished span of bridge is due to open by 5 AM Tuesday at the latest, nearly 25 whole years after the 6.9 magnitude Loma Prieta quake took out a chunk of it back in 1989. The modified bridge is designed to handle the strongest possible quake that's likely to hit the area within the next 1,500 years.

It's been a long, hard, delay riddled road to completion, one that took a lot longer than 4 minutes to travel. But wow is it ever incredible to see it coming together before your very eyes. [EarthCam, ABC News]
